SHADE ROLLER Fiied Dec. 18. 1942 Patented Dec. 7, 1943 SHADE ROLLER Grace M. Price, Chicago, Ill., assigner to American Patents Syndicate Inc., Chicago, Ill., a corporation of Illinois Application December 18, 1942, Serial No. 469,738

Claims.

This invention relates to a shade roller adapted for placement above a window for supporting a shade or curtain or the like and concerns itself primarily with means for attaching the shade or cur-tain to the roller whereby such Shade or curtain can be quickly and readily applied or removed and replaced without the use of tacks or nails or similar securing means.

I am aware that it is old to form a groove in a shade roller and anchor the beaded end of a curtain in a recess in such groove by a bar on a hinge plate such for example as is shown in Patent No. 1,333,906 of March 16, 1920. In Such a construction, it is necessary to hem an anchor Y rod in the attaching margin of the curtain for lodgment in the recess of the groove in which it is locked by the bar.

This invention diiers from such prior constructions in that no bead or similar means are required on the attaching margin of the curtain which is yieldingly maintained in frictional clamping relation with the roller, preferably aided by a shoulder forming one wall of the groove in the roller.

According to this invention, a groove or depression is formed lengthwise in the roller and a yieldingly hinged arcuate clamping plate is attached to the roller and this plate is yieldingly urged over the groove or depression; said plate having a portion or rib extending into the groove or depression for wedging or clamping the attaching margin of the curtain or shade in the groove or depression in frictional relation therewith.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and deiined in the appended claims.

In the accompanying drawing which illustrates certain preferred forms of this invention and in which similar reference numerals refer to similar features in the diiTerent views:

Fig. 1 is a perspective of a shade or curtain roller embodying this invention.

Fig. 2 is an enlarged sectional View taken upon the line 2--2 of Fig. 1 looking in the direction of the arrows.

Fig. 3 is an enlarged part sectional and part perspective view of a slightly modiiied form of shade roller involving this invention.

Fig. 4 is a sectional view of a further modified form of the invention.

Fig. 5 is a sectional View taken upon the line 5--5 of Fig. 4 looking in the direction of the arrows and Fig. 6 is a sectional view of a further modification of the invention.

In referring now to the drawing, there is shown in Fig. 1, a wooden shade roller I having an arcuate groove 2 extending lengthwise thereof; in the present instance, the groove extends to the ends of the roller.

A clamping plate 3 is suitably hinged to the roller and is curved so as to correspond to the curvature of the roller and it is provided with an arcuate portion or rib 3a which is adapted to fit snugly in the groove 2. This clamping plate may be hinged to the roller in various ways. A simple way consists in forming hinge slots or holes 3b in the margin to be hinged and driving staples 4 into the roller with one leg of each staple extending thru a hole 3b in the clamping plate. Any suitable type of yielding means may be used for yieldingly urging the clamping plate against the roller. In the present instance, I have illustrated curved leaf springs 5 attached to the roller I adjacent the hinge edge of the clamping plate and extending transversely over portions of the clamping plate. These springs 5 will urge the clamping plate against the roller with the rib 3a nesting in the groove 2 and frictionally binding the attaching margin of the curtain 6 therein. In Figs. 1 and 2, the roller is not shown as countersunk for the clamping plate although the roller may be countersunk for such a purpose if desired.

In Fig. 3, there is sho-wn how the invention can be applied to a hollow metal roller l. In this form, the clamping plate 8 is shown as provided upon its hinge edge with downwardly oifset hinge eyelets 9 extending thru holes It in the roller. At suitable points, pockets Il may be stamped down in the roller in alinement with the eyelets for forming bearings for a hinge rod I 2 which extends thru the hinge eyelets 9. As shown, a pocket is preferably formed upon each side of hinge aperture. However any other suitable method may be used for hinging the plate to the roller.

The plate 8 is shown as provided with a rib or portion 8a tting in a longitudinally extending groove I3 in the roller l.

The clamping plate 8 is normally urged against the roller I by yielding means of any suitable character and as a matter of illustration, I have shown resilient or spring clips I4 which snap over the roller and over transverse portions of the plate 8 for yieldingly urging the same against the roller with the rib 8a nesting snugly in the groove or depression I3. The attaching margin of the curtain or shade B is shown as positioned between the plate and roller with a portion frictionally clamped in the groove I3.

In Fig. 4, there is shown a slight modification of the structure for performing the function pointed out. In this form of the invention, a metal rollerI I5 is shown which may have a countersunk portion I5a for receiving a spring clamping plate I6. This clamping plate is shown as provided upon its hinge edge with spaced spring tongues |611 which extend through slots I'I in the roller and engage the wall of the roller at their ends and which serve as yieldinghi'nge anchors. While this clamping plate will frictionally anchor the curtain 5, it may be desirable in some instances to use additional anchoring means and in such an event, pins Ib or the like may be incorporated in the clamping plate and suitable apertures I3 made in the roller to receive the points of the pins. that the countersunk portion of the roller which terminates at its lower edge in a shoulder forms a depressed portion in which the attaching margin of the curtain B is confined.

In Fig. 6, a further modification has been illustrated in which a clamping plate I@ provided with eyelets 9 similar to the ones shown in Fig. 3 and similarly hinged upon a rod I2. The clamping plate I9 however differs from the plate S shown in Fig. 3 in that it is provided with a lengthwise slot 2li thru which the attaching margin of the curtain is adapted to be threaded and folded about the lower margin of the plate.

It will be noted that the roller ZIB has a longitudinally extending depression 23a which terminates in a shoulder 2do at its lower edge, and that the clamping plate IQ is fashioned to correspend Withthe shouldered portion of the depression in order to frictionally Wedge or clamp the curtain in such depression. In order to yieldingly urge the clamping member lil against the roller, spring clips Id. maybe snapped over the roller and over transverse portions of the clamping memberf I9 as shown in Fig. 6; However any other suitable yielding means may be used.

In the use of a curtain or shade roller involving this invention, it is merely necessary to elevate the clamping plate against the tension of the yielding means and insert the upper margin of the curtain under such plate to a suitable extent and then release the plate allowing the yielding means to quickly snap the plate back against the roller and thereby wedging a portion of the curtain in the depression beneath the clamping means and frictionally anchoring the same to the roller.

In the event that it is desired to remove the curtain for washing or for replacement by a new curtain or for any other purpose, this can easily It will be appreciated i and quickly be done by simply lifting the clamping plate sufficiently for the withdrawal of the curtain.

I am aware that many changes may be made and various details of construction modified without departing from the principles of this invention so I do not propose limiting the patent granted thereon otherwise than necessitated by the prior art and appended claims.

I claim as my invention:

1. In a device for suspending a sha-de, a roller, a clamping member hinged upon a longitudinal axis upon the roller, yielding means acting upon said member for urging the same against said roller, said roller and member having co-operating surfaces adapted for frictionally clamping the margin of a shade therebetween.

2. In a device for suspending a shade, a roller having a longitudinally extending shouldered depression, a clamping member hinged to said roller and having a portion adapted for extending into said depression in contacting relation with that shoulder thereof most remote from the hinge margin, and yielding means normally acting upon said member for urging the same against the roller adapted for frictionally clamping a margin of said shade in said depression.

3. In a device for suspending a shade, a roller, a clamping strip hingedly attached to said roller for relative movement with respect thereto and yielding means for normally urging said strip against said roller, said strip being adapted for movement away from said roller against the force of said yielding means for the insertion of a margin of said shade between said strip and roller, and said roller and strip having interengaging means upon their confronting faces for osetting a portion of the margin of said shade for rmly anchoring the shade to said roller.

4. In a device for suspending a shade, a roller having a longitudinally extending depression, a clamping member hinged to said roller and having an offset portion extending into said depression, said depression having a shoulder at one edge and yielding means acting upon said clamping member for urging the same against said roller adapted for frictionally clamping a margin of said shade in said depression and over said shoulder.
